(LFT (R) series) 5th generation low torque tapered roller bearing LFT-V development company release

Category: Goods and services

Release issuing company: JTEKT Corporation

JTEKT Corporation (hereinafter referred to as JTEKT) boasts the No. 1 low torque performance in tapered roller bearings used for automobile transmissions and pinion support for differential units, and is the lightest next-generation product in the series, LFT-. Developed V. Focusing on automobile manufacturers around the world, we will contribute to lower fuel consumption and higher efficiency of automobiles, and will continue to make global proposals as products that also support EVs. * LFT is an abbreviation for Low Friction Torque and is a registered trademark of JTEKT. [Development background] Tapered roller bearings used in automobile transmissions and differentials are used in oil, but the conditions of use are particularly high in lubrication oil viscosity, high lubrication amount, and high rotation speed. There was a problem that the stirring loss of the lubricating oil increased due to the pumping action of the bearing. Therefore, J-Tect focused on reducing the stirring loss of lubricating oil, and realized a significant reduction in torque by suppressing the amount of lubricating oil flowing into the bearing. "3rd generation low torque tapered roller bearing (LFT-III)" ) ”,“ 4th generation low torque tapered roller bearing (LFT-IV) ”has been developed and commercialized. In order to meet the need for further low fuel consumption, we have optimized the shape of the resin cage and optimally controlled the inflow of lubricating oil to achieve the No. 1 low torque performance and the cage. A groove that can hold oil is provided in the pocket to improve seizure resistance at start-up and low temperature, and to optimize the oil flow inside the bearing in anticipation of the recent low-viscosity oil reduction and oil volume reduction. As a result, we have developed the "5th Generation Low Torque Conical Roller Bearing (LFT-V)" that can reduce the temperature rise of the bearing. [Features of the developed product] ● Tapered roller bearing-LFT series No. 1 * Performance achieved by optimizing the shape of the resin cage. ● Space-saving, low-torque design support is possible without changing peripheral parts, achieving the lightest weight in the tapered roller bearing-LFT series. ● Bearing performance 3. Sales plan [Start mass production] Aiming for 2022 [Sales target] 1.7 million sets / year (2025) [Sales destination] Domestic and overseas automobile manufacturers, transmission manufacturers, etc. 4. Reference Generation evolution of LFT series JTEKT has set "Key of your operation" in the bearing business brand "Koyo", and as a partner who solves problems together with customers and provides joy, bearings that adapt to various environments. We will continue to contribute to all industries.To the details of the company press release, to the PR TIMES top
